I probably don’t have to tell you about the benefits of green smoothies. These days nothing makes you look cooler than holding a green-tinted beverage, outside of St. Patrick’s Day. Besides the obvious trendy points, adding some leafy greens to your smoothie is a great way to sneak in some additional iron, fiber and plenty of vitamins to your day. Just make sure to avoid adding a lot of artificial ingredients and excess sugars or you kind of lose the point.

This is all green and great but always having a fresh bushel of spinach and kale on hand isn’t exactly feasible, especially since they spoil so fast. Solution? Kale cubes of course! Simply pre-puree your greens into handy ice cubes. This way you’ll always have greens on hand to pop in a smoothie, even if you haven’t been to the grocery store in two weeks.

These cubes were inspired by the type of people that freeze coffee into ice cubes to add to their iced coffee so that it doesn’t get watered-down (genius). Feel free to use any type of leafy green you have available but kale and spinach seem to work the best. Pre-pureeing greens also guarantees there won’t be chunks of kale or spinach strings in your smoothie and most, if not all, of the veggie taste will be masked.
